Illinois, have invented certain new and use,

ful Imprvementsin Refrigerator-Cars, of which the following is a specification, and

drawings, forming a part thereof.

The invention relates to refrigerator cars of the convertible type, in which the inner wall of the ice bunker takes the form of a an improved 'form of construction increasing the ease and convenience of shifting the bulkhead an improved arrangement of the ice supporting grating; and improved means for guarding the icing aperture when used for the purpose of ventilation.

L The invention consists in a structure such as hereinafter described, -and as illustrated' in the accompanying drawings, in which- Figure 1 is a detail longitudinal vertical section of a car; v

Fig. 2 is a detail of the ice-supporting grating; 'V

Fig. 3 .is a detail transversevertical sec` tion of the car loolng toward the ice bunker, some parts being shown in elevation and some parts being broken away;

Fig. 4 is a detail section on the line 4-4 of Fig. 3;

Fig. 5 is a plan view of one ofthe ice gratings; and

Fig. 6 is a view in perspective of a grated screen for the ice opening.

v The bottom, end wall and roof of a carv are shown, respectively, at 10, 11, 12. The

bulkhead forming the inner wall of the ice bunker is represented at 13, and is preferably faced on the outer side with slats 14 and at its inner surface with a heavyv wire mesh 15. This .bunker may be constructed in any desired manner,as, for example, with inclined air ducts,as indicated in dotted lines at 16,4 following the type known as'the Pries si hon.`

The side of the car, and is su ported on tracks 17, 18 and 19 extending ongitudinally of Abulkhead in its advance position.

ulkhead 13 extends from side to the car, by means of rollers 20, 21, 22, riding on such tracks, whereby the bulkhead may be moved to the outer or service osition shown in solid lines in Fig. 1, to orm the inner wall of the ice bunker, or may be moved backwardly -acglainst the end of the l icated in dotted lines 1n said'jfigure, leavin the body of thercar` or lthe reception of' car to the position in substantially clear freight.

Wall plates 23, 24, are xed to the side walls of the car to receive bolts 25, carried by the bulkhead, when the latter is in either of its positions. A bolt 26, located at the lower margin of the bulkhead, coperates with a fixed socket 27 for securin the n ocket plates 28, attached tothe side walls near the end of the car, coperate with laterally the carin line with the forward position of the bulkhead, and closes the space below 'the latter. Preferably this rail is vfaced with metal, as shown, and to it the-socket plate 27 is attached. This rail forms the front wall or splash rail of a well for receiving the drippings from the ice, such drippings being discharged through any suitable outlet, 'such as the trapped `disvcharge tube 30.

The ice grating 31 takes the form of a pair offrames with cross-bars, which together extend from side wall to side wall of the car and from the end wall thereof to thel inner face of the bulkhead when the latter is in its service position. These frames are supported by legs 32, 33 and 34,

-four being adequate for the purpose, each of which is pivoted to a cross-member of the grating in order that it may be downably also the legs adjacent the end of the car are notched at their hub portions, as shown at 36, 37, for the engagement by a latch 38 pivoted to the grating, which thereby locks the leg in either of its positions. l

The bulkhead is capable of being swung forwardly from its service position, as indicated by dotted lines in F ig. l, a socket plate 39 being fixed to the side of the car for .receivin the bolts 26a to hold it in a somewhat e'evated position to permit access to the bunker for the purpose of cleaning out the ice and raising and lowering the grating.

Icing apertures, as 40, are provided in the top of the car above the bunker, and when the car is being used for freight not requiring refrigeration, the bulkhead being in its retracted position, these apertures may be left o en for Ventilating purposes, and when t us used are required to be guarded to prevent unwarranted access to the 1nterior of the car therethrough. There is accordingly provided a screen 41, associated with each of the icing apertures and being hingedly attached to the car roof, as shown at 4:2, "adjacent the margin of the opening most remote from the end of the car, the screen being of suliicient length` to entend entirely across the opening when swung upwardly. service position these screens swing downwardly against its inner face As the bulkhead is moved back to storage position it forces the-screens upwardl to the position shown in Fig. 4. To facilitate this action each of the screens is provided with a pair of wear plates 43, 44, along which the upper margin of the bulkhead will slide. At the :tree end of the screen each of these wear straps may be bent downward, as shown at 45, in order that as the bulkhead comes in contact with the end wall of the car the screen will be cammed upwardly tightly against the car roof.

Cars of this character are frequently used for the transportation of perishable freight, such as fruit and vegetables, notrequiring refrigeration butin connection with which ventilation is necessary. rlhe lloor of, the car is consequently usually provided throughout with a slatted grating 46, and the splash rail 29 will be made of a height corresponding to the thickness of this grating. lflhen, therefore, the bulkhead 'is shifted backwardly the ice grating and rail form a continuation of the ooring of the body of the car and at the same level.

The construction shown and described, while preferable, may be deviated from as When the bulkhead is in accenna 'when its legs are folded upwardly.

2. The combination with a car body, of a rail fixed transversely to the car door and formin the front wall of a drip well for an ice unker, a bulkhead movable from a position immediately above the rail to a position against and parallel with the end wall of the car, a vertically adjustable grid adapted to lie between the rail and the end i wall of the car when in its lower position and folding legs for supporting the grid in elevated position and engaging the same adjacent each edge and being inclined outwardly with reference to the grid when in' service.

' 3. In a refrigerator car, the combination with side and end walls thereof, of a bulkhead carried by the side Walls and bodily movable from an upright position against the end wall to an upright position away from such wall, and being adapted to swing upwardly from its latter position, and

means for supporting the bulkhead when thus swung upwardly.

4. ln a convertible refrigerator car having an icing opening, a bulkhead movable in a vertical position from the end wall of the car forwardly to form the front wall of an ice bunker, and a screen hinged to the car adjacent the inner margin of the ice o cning and back of the service position o the bulkhead, such screen beingy adapted to be swung upwardly by the bulkhead in its movement toward the car end, and to extend across the opening.

5. rlhe combination with a car body, of a rail iiXed transversely to the car door and forming the front wall of a drip well for an ice bunker, a false iloor forward of and approximately flush with the u per face of the rail, a bulkheadA movable rom a position immediately above the rail to a position against and parallel with the end wall of the car, and a vertically adjustable grid adapted to lie between the rail and the end wall of the car when in its lower position, its upper surface when so disposed being approximately ush with the upper surface ot the rail.
